Coding missing values in Royle point-count occupancy models

Postby ajpaul » Thu Jan 19, 2012 4:35 pm

Thought this would be an easy problem to resolve but have turned up empty handed after a couple of searches on the forum and elsewhere. Apologies in advance if my search skills are lacking.

How do you code missing values in the Royle point-count occupancy models (OccupRNegBin or OccupRPoisson)? These models require count data and MARK reads in pairs of characters from 00 to 99 for each occasion (i.e., a count of 2 is coded 02). This is clearly described in the Donovan exercise 8 example

>?Donovan.8

However, how would missing values be coded in this paired format? I tried ".." and "." but with no luck. I did read in the forum that PRESENCE allows coding of missing values in the Royle point-count models, so I'm hoping that's the case with MARK and RMark?

Thanks for your help,
Andy

RMark now allows a ".." in the input for those models. The patched version is on my github site

https://github.com/jlaake/RMark/downloads

and I'll post to CRAN shortly.

When posting a message about RMark, please provide the function being run and the error message. If I cannot work out the problem from that I'll ask you to send the R code and a snippet of the data. I didn't realize from this post that RMark was generating the message.
